Randomized Controlled Trial
Propofol plus low dose dexmedetomidine infusion and postoperative delirium in older patients undergoing cardiac surgery.
Postoperative delirium (POD) is a frequent complication in older patients. Dexmedetomidine might be effective in decreasing the incidence of POD. We hypothesised that adding low-dose rate dexmedetomidine infusion to a propofol sedation regimen would have fewer side-effects and would counteract the possible delirium producing properties of propofol, resulting in a lower risk of POD than propofol with placebo. ⋯ NCT03388541.

Randomized Controlled Trial
Perioperative use of physostigmine to reduce opioid consumption and peri-incisional hyperalgesia: a randomised controlled trial.
Several studies have shown that cholinergic mechanisms play a pivotal role in the anti-nociceptive system by acting synergistically with morphine and reducing postoperative opioid consumption. In addition, the anti-cholinesterase drug physostigmine that increases synaptic acetylcholine concentrations has anti-inflammatory effects. ⋯ EudraCT number 2012-000130-19.

Randomized Controlled Trial Multicenter Study
Multicentre randomised controlled clinical trial of electroacupuncture with usual care for patients with non-acute pain after back surgery.
The purpose of this study was to investigate the effectiveness and safety between electroacupuncture (EA) combined with usual care (UC) and UC alone for pain reduction and functional improvement in patients with non-acute low back pain (LBP) after back surgery. ⋯ KCT0001939.

Randomized Controlled Trial
Phenylephrine impairs host defence mechanisms to infection: a combined laboratory study in mice and translational human study.
Immunosuppression after surgery is associated with postoperative complications, mediated in part by catecholamines that exert anti-inflammatory effects via the β-adrenergic receptor. Phenylephrine, generally regarded as a selective α-adrenergic agonist, is frequently used to treat perioperative hypotension. However, phenylephrine may impair host defence through β-adrenergic affinity. ⋯ NCT02675868 (Clinicaltrials.gov).
